7318 BEGAPH Bearing Product Overview & Core Advantages
The 7318 BEGAPH is a single row angular contact ball bearing designed for high-precision applications requiring superior performance under combined loads. This precision bearing excels in handling significant axial loads in one direction alongside radial loads, thanks to its optimized 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and rotational stability. The bearing comes pre-lubricated and features a nylon cage for reduced friction and smooth operation at high speeds up to 4,500 rpm. Its robust construction ensures high rigidity and reliable performance in demanding industrial environments.

7318 BEGAPH Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The BE design features precisely calculated raceway curvatures and ball complement that maximize load distribution and minimize stress concentrations, resulting in extended service life.
High Axial Load Capacity: With a 40° contact angle, this bearing efficiently handles substantial one-direction axial loads while maintaining excellent radial load capacity, making it ideal for applications with combined loading conditions.
Superior High-Speed Performance: The nylon cage (PH) provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling smooth operation at limiting speeds of 4,500 rpm. The cage design ensures proper ball guidance and minimal friction.
Precision Manufacturing: Manufactured to P6 tolerance class (ABEC-3), this bearing guarantees precise dimensional accuracy and consistent performance, crucial for applications requiring minimal runout and vibration.
Robust Material Construction: Both rings and balls are manufactured from chrome steel, providing high hardness, wear resistance, and durability under demanding operating conditions.
